PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 625,470, dated May 23, 1899.

Application filed August 30, 1893- Serial N0. 484,358. (No model.)

To all whom, it may concern:

Be it known that LWALTER SCOTT, a citizen of the United States, and a resident of Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Printing-Machines, of which the following is a specification.

The invention relates,primarily,to printingpresses wherein several colors are printed on one or both sides of the web, and has for its objects the simplification and improvement of this class of printing-machines, the oiling of a number of impression-cylinders from oneoil-fountain, the prevention of the transfer of color from one part of the web or sheet to another non-corresponding part of the same, and other objects, as will hereinafter appear.

To these ends the invention consists of the combination, with a plurality of impressioncylinders, of an oil-fountain and means supplying oil therefrom to the said cylinders and hereinafter more particularly described and claimed.

The invention is shown in the accompanyin g drawings, forming part hereof, in which- Figure 1 is a side view of the printing mechanism, no framework being shown. Fig. 1

is a view of the oiling devices shown in Fig. 1,

but in a different position of the parts. Fig. 2 is a side view of part of the machine, showing part of the operating mechanism for the oilers. Fig. 3 is a like View taken on a vertical plane inside that of Fig. 2, omitting the framework and showing the remainder of said mechanism. Fig. 4 is a side view of the printin g mechanism of a modification of the invention shown in Fig. 1.

Referring to the accompanying drawings, a press adapted to print upon one side of a web is shown at A, the said press consisting of the impression-cylinders 1 and 2, the plate or type cylinders 3 4: 5, coasting with the cylinder 1, plate-cylinder 6, coacting with impression-cylinder 2, and the usual inking apparatus for each plate-cylinder. The web w may be led to this machine from a roll (not shown) about rollers 7 8 9 and over tapes 10 to and between the cylinders 1 3; but 1 prefer to first lead the web to the printing-machine B as over roller 11. The machine 13,

which is below machine A, consists of impression-cylinders 12 13, their coacting platecylinders 14 15, and the usual inking devices. From machine B the web 10 passes around roller 9 to machine A. This roller 9 may be mounted iii-pivoted arms and so act as a web take-up to obtain register of the impressions of the two machines; but I prefer the con- I struction hereinafter described for a take-up.

After leaving cylinder 2 the web may lead about roller 16 to a suitable cutting and folding mechanism or between cylinders 13 15 and about roller 17 over tapes 18 to a like mechanism. During its course through the two machines the web will have received impressions on one side from cylinder 14 and impressionsv in diiferent colors on the other side from the cylinders 3, 4, 5, 6, and 15 or such of them as have forms on them.

The various cylinders of each machine are geared together in the usual manner, the power required to drive them being applied to the shaft to of the cylinder 13. The gear I) of cylinder 13 is connected by the iuterme' diate gear 0 with the gears d e of the cylinders 1 2. (See Fig. 2.)

For the purpose of preventing set-01f on the cylinders 1, 2, and 13, and so to the web, the cylinders are oiled. Each cylinder may have its own independent oiling devices; but I pref fer to oil them from a common oil-supply by suitable means. The means for this purpose (shown in Figs. 1, 2, and 3 of the drawings) will now be described. The oil-fountain 19 has a fountain-roller 20 therein, from which the vibrating doctor 21 takes oil at intervals and supplies the roller 22 therewith. The roller 22 is mounted for rotation in the framework of the machine. From roller 22 the oil is taken by the vibrating rollers 23 24 25,which in turn apply the oil to cylinders 1, 2, and 13, respectively. These various rollers may receive their motion in'any suitable way. The

an antifriction-roller 33, which coacts with cam 30. A link 34 connects arm 31 with a lever 35, journaled on the shaft 36 of fountain-roller 20. A pawl 37 on lever 35 coacts with ratchet 38, fast on the shaft 36, to turn the roller 20. The roller 33 is kept in contact with cam 30 by the weight of arm 31 or a spring, (not shown,) or both. A rock-arm 39, pivoted on shaft to the framework, carries an antifriction-roller 41, which also engages cam 30. A link 42 connects arm 39 with arm 43 of the rock-shaft 44, which has arms 45,carrying theductor-roller21. An arm 46 is connected by link 47 with an arm 48 of shaft 49. This shaft 49 has arms 50, which support the roller 25. The arm 46 is fast on a short shaft 40, which is connected with cam 29. the loose sleeve 53 on shaft 28 and carries a roller 54, which engages groove-cam 29. It also has a slot 55, which engages a pin 56 on arm 57 of shaft 58. This shaft 58 has arms 59, which carry roller 24. The slide 51 has two lugs 60, which engage a head 61 on arm 62, which is fast to shaft 40. It also has two other lugs 63, which engage head 64 of arm 65 of rock-shaft 66. Arms 67 on shaft- 66 support the roller 23. The various parts are so timed that the whole impression-surfaces of the cylinders are oiled in proportion to their requirements. Figs. 1 and 3 show rollers 23 25 as taking oil from roller 22 and roller 24 as oiling its cylinder. Fig. 1" shows an inversion of positions of these parts.

In Fig. 4 is shown a modification of the arrangement shown in Fig. 1. An impressioncylinder 68 is placed between the plate-cylinder 3 and cylinder 1 to form machine A while the lower machine B is unchanged. The web 20' leads, as shown, through machine A and may lead thence to a cutting and folding machine, or it may lead to machine B around roller 69, the take-up T, and to and between either cylinders 12 14 or 13 15. The

web 10 may be used when machine A delivers around roller 16, as hereinafter described. The take-up T consists of end pieces 70, tieshafts 71, and journals 72, and rollers 73 on The slide 51 has a slot 52, which fits over said presses, whereby one web may be run through all said presses to be printed upon, as the same forms the subject-matter of claims in my application for Letters Patent filed on the 23d day of November, 1894.

I remark that when more than two impression-cylinders are used in giving the multiple impressions on one side of the web or sheets their axes can be arranged in closed geometrical figures-as triangles, quadrilaterals,

&c.according to the number employed and that the oiling devices can be placed partly or wholly within such figures, thus economizing space.

Vhat I claim is In a printing-machine, the combination of three or more impression-cylinders arranged in a closed geometrical figure, an oil-fountain and means for supplying oil therefrom to said cylinders, said oiling devices being partly or wholly within saidfigure, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 22d day of July, 1893.

WALTER SCOTT.
